Dealing with a vehicle emission test failure can be frustrating. If you’ve encountered a “Readiness Fail 3” result, especially related to your vehicle’s monitors not being ready, you’re likely looking for answers. This guide from the experts at keyfobprog.com will break down what “readiness fail 3” means, why it happens, and what you need to do to get your vehicle passing inspection.
What Does “Readiness Fail 3” Mean?
In the context of vehicle emissions testing, a “Readiness Fail” indicates that your car’s onboard computer hasn’t completed self-tests on its emission control systems. These self-tests are called “readiness monitors.” The “3” in “Readiness Fail 3” is crucial: it refers to the number of “Not Completed” readiness monitors that will cause your vehicle to fail the inspection, depending on its model year and fuel type.
To pass an emissions test, your vehicle needs to show a “Readiness Result: Pass.” However, if too many monitors are in a “Not Completed” state, the result will be a “Readiness Result: Fail.” Understanding the thresholds for failure is essential.
Readiness Monitor Failure Thresholds
The number of “Not Completed” monitors that trigger a “Readiness Fail” depends on your vehicle’s specifications:
| Vehicle Type | Model Year Range | # of “Not Completed” Monitors for Fail |
|---|---|---|
| Gasoline Powered | 1996 – 2000 | 3 or more |
| Gasoline Powered | 2001 and Newer | 2 or more |
| Diesel Powered | 1997 to 2009 | 1 or more |
| Diesel Powered | 2010 and Newer | 2 or more |
Therefore, “readiness fail 3” specifically points to gasoline-powered vehicles manufactured between 1996 and 2000 having 3 or more readiness monitors in a “Not Completed” state. If your vehicle falls into this category and shows 3 or more incomplete monitors, you will receive a “Readiness Result: Fail”.

Why Are Readiness Monitors “Not Completed”?
Readiness monitors are designed to run self-diagnostics on various emission control systems in your vehicle. They must complete these tests to confirm that these systems are functioning correctly. Several common reasons can lead to monitors being “Not Completed”:
- Recent Battery Replacement or Disconnection: Disconnecting or replacing your car battery resets the vehicle’s computer memory, including the readiness monitor status.
- Diagnostic Trouble Code (DTC) Clearing: Repair shops often clear DTCs after repairs. This action also resets the readiness monitors.
- Power or Grounding Issues: Problems with your vehicle’s electrical system can disrupt the computer’s ability to run self-tests.
- Unmet Driving Conditions for Testing: Each monitor has specific “drive cycle” requirements – a set of driving conditions that must be met for the self-test to initiate and complete. These can include specific speeds, durations, and engine temperatures.
- Underlying Emission System Problems: Sometimes, a monitor is “Not Completed” because there’s an actual issue with the emission system that prevents the self-test from running or completing successfully, even before triggering the “Check Engine” light.
- Aftermarket System Installation: Improperly installed aftermarket parts can interfere with the vehicle’s computer and emission system monitoring.
- Software Updates: Vehicle computer software updates can sometimes reset readiness monitors.
Resetting Readiness Monitors to Pass Inspection
The good news is that often, “Not Completed” monitors can be resolved by simply driving your vehicle. The vehicle needs to be driven in a way that allows its computer to run through the necessary drive cycles for each monitor.
General steps to reset monitors:
- Drive Regularly: Normal city and highway driving over 4-7 days is often sufficient to reset most monitors.
- Consult Your Owner’s Manual: Your owner’s manual may contain specific drive cycle information for your vehicle make and model. This can provide more precise instructions on how to complete the drive cycles efficiently.
- Avoid Aggressive Driving: Smooth, consistent driving is generally better for completing drive cycles than hard acceleration and braking.

30-Day Extension for “Readiness Fail”
Many jurisdictions understand that resetting readiness monitors takes time. If your vehicle fails only due to “Not Completed” readiness monitors, you may be granted a temporary extension to get your monitors ready.
30-Day Extension Policy:
- Drive Legally: You may be allowed to drive your vehicle for up to 30 days beyond your registration expiration to reset the monitors.
- Carry Test Report: Keep your vehicle inspection report that shows the “Readiness Fail” result. Present this to law enforcement if needed to prove you are in the process of resetting monitors.
- Address Safety Issues: Ensure your vehicle passes any required safety inspection. The 30-day extension typically applies only to emissions readiness, not safety.
- Avoid Late Fees: Start the inspection process as soon as possible to avoid potential late registration fees.
Important Note: This 30-day extension is specifically for “Readiness Fail” due to incomplete monitors. If your vehicle fails for other reasons, such as a “Check Engine” light or high emission readings, this extension may not apply.
When Monitors Don’t Reset: Seeking Professional Help
If you’ve driven your vehicle for a week or more under various conditions and your readiness monitors are still “Not Completed,” there might be an underlying issue.
Next Steps:
- Qualified Emissions Technician: Take your vehicle to a qualified emissions technician. Explain that you are experiencing a “Readiness Fail” and that monitors are not resetting.
- Provide Information: Inform the technician if your “Check Engine” light was on recently, if any repairs have been performed, or if the battery was recently replaced.
- Diagnosis and Repair: The technician can diagnose why the monitors are not completing their self-tests. This may involve checking for DTCs, examining the emission control system, and verifying proper computer function.
No Waivers for Readiness Issues
It’s crucial to understand that, according to EPA guidelines, there are no waivers for readiness monitor failures. Unlike some emission component failures that might qualify for waivers based on repair costs, a “Readiness Fail” due to “Not Completed” monitors must be resolved for your vehicle to pass inspection. This means getting the monitors to a “Completed” state is mandatory.
Conclusion
Encountering a “Readiness Fail 3” during your vehicle inspection can be a temporary setback. Understanding that it often stems from incomplete readiness monitors and knowing the steps to reset them can save you time and stress. Remember to drive your vehicle to allow the monitors to complete, and utilize the 30-day extension if available while you work to resolve the issue. If the monitors persist in showing “Not Completed,” seek professional diagnosis to ensure your vehicle’s emission system is functioning correctly and to get your car ready for a passing emissions test.
